Claude a5085cc65b Self-install a PATH wrapper so setup.sh works from any directory
Every invocation of setup.sh (bare, --list/--status, or with a service
name) now ensures /usr/local/bin/post-install exists and execs this
checkout's setup.sh by its real resolved path -- idempotent (only
writes when missing or pointing somewhere else) and silent except for
a one-line notice the first time it's actually created. Previously
this required cd'ing into the repo (or a manually-created wrapper) on
every box separately; now it's automatic on first run, no separate
setup step.

A plain symlink wouldn't have worked here: setup.sh finds its own
directory via ${BASH_SOURCE[0]}, which bash doesn't resolve through
symlinks, so a symlinked invocation would have set HERE to the
symlink's own directory instead of the repo's.

# setup.sh — modular post-install dispatcher.
#
# One source of truth, multiple ways to run it:
# sudo ./setup.sh guided install: required packages, then a
# category menu you loop through
# sudo ./setup.sh <service> ... install one or more services directly
# ./setup.sh --list list available services (grouped)
# ./setup.sh --status list services with install status (no whiptail)
# ./setup.sh --version print version
#
# Flags:
# --dry-run preview actions without making changes
# --unattended use defaults, no prompts (pair with explicit service names)
# --remove remove instead of install (pair with a service name, e.g.
# ./setup.sh filebrowser --remove, or the plain word "remove"/
# "uninstall" works too: ./setup.sh filebrowser remove) —
# stops/removes its containers, its Caddy site block (if
# any), any UFW rule tagged for it, and optionally its
# ~/docker/<name> directory
#
# Every service lives in services/<name>.sh, registers itself with
# register_service, and defines install_<name>. Adding a service = adding one
# file; it appears in the menu automatically. Nothing is generated.
